PLAY ACCOUNTING+ Trophy
Get very deep into the numbers.
This one is a little more involved than the others, but it is still very simple if you know what you need to do.
When you first enter tree world, open the bird house and pick up the seed inside of it. Turn around and plant the seed in the pot to make a small plant grow. Now, just play through the game however you wish until you come back to tree world.
Once you're back, an apple will have sprouted from the plant that you'll have to pick up. Turn the apple around and - suprise! - it's another pair of VR goggles that you can use! All that you have to do now is finish the secret level and the trophy is yours.
